Well, after lots of trying, I have gotten a bit further. I can boot the fedora installer dvd, then switch to a shell, load the necessary modules and create the device nodes using this script. Unfortunately, the driver then wants to continue installing on /dev/hdg and not on /dev/ataraid/d0. So, I temporarily remove /dev/hdg and link it to /dev/ataraid/d0 to fool the Anaconda installer. Once it figures out that it should use /dev/ataraid/d0, I move the files back before doing any partitioning. But.... Anaconda crashes on a KeyError: ataraid/d0 when I try to modify the partitioning. However, I can use fdisk to partition the disk. Now, I need to figure out how to trick the installer into using ataraid devices.
